Obesity and poor reproductive outcome: the potential role of the endometrium
2007
Objective To analyze the potential role of extraovarian factors such as endometrium in the reproductive outcome of obese patients. Design Retrospective study. Setting University-affiliated infertility clinic, between January 2001 and July 2005. Patient(s) Women undergoing a total of 2656 first ovum donation (OD) cycles with good quality embryos. Intervention(s) The oocyte donors underwent controlled ovarian hyperstimulation, and recipients received a well-established hormonal replacement therapy for endometrial preparation. In vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) was performed according to semen characteristics. All first cycles (n = 2656) of ovum donation us…
Diagnostic genetic screening for assisted reproductive technologies patients with macrozoospermia
2017
International audience; Macrozoospermia is characterized by a high proportion of abnormal spermatozoa with enlarged heads. So far, it has been associated with mutations only in the Aurora Kinase C gene (AURKC) in some cases. Although many publications have reported failure to conceive in couples with macrozoospermia, a few others have described successful pregnancies, thus raising questions as to whether ICSI and AURKC genetic screening should be recommended in all patients with macrozoospermia. First, we report on two monozygotic twins presenting macrozoospermia for whom the genetic status was explored (Aurora Kinase C sequencing) and whole semen and gradient-selected spermatozoa were anal…
Primordial Prevention of High Blood Pressure in Childhood
2020
Hypertension is a condition with increased risk for subsequent adverse events, and treatment of hypertension is prescribed for primary prevention of adverse events. Primordial prevention is a concept that precedes primary prevention and focuses on risk factor prevention. Primordial prevention of hypertension consists of strategies to maintain blood pressure in a normal range and prevent development of elevated blood pressure or hypertension. Childhood is a period in which primordial prevention could be effective and if sustained throughout childhood could contribute to a healthier young adulthood. Targets for primordial prevention in childhood include preventing and reducing childhood obesi…
New options in assisted reproduction technology: the Cryotop method of oocyte vitrification
2008
The Cryotop vitrification method has been shown to be a very useful tool for oocyte cryopreservation, giving excellent results regarding survival and clinical outcome. There are several clinical situations in which oocyte cryopreservation provides solutions that have not been available to date. This report describes three of these situations: (i) a low-responder patient who needed a single gene diagnosis due to the presence of a genetic disease; (ii) a patient undergoing endometrial bleeding on the day of oocyte retrieval who was also affected by a genetic disorder; and (iii) a patient who failed to become pregnant after the donation of vitrified oocytes and subsequently had the re-vitrifie…
First report of the absence of viral load in testicular sperm samples obtained from men with hepatitis C and HIV after washing and their subsequent u…
2008
Human immunodeficiency virus and hepatitis C infections are sexually transmitted diseases that require sperm samples to be pretreated to eliminate the viral presence before their safe use in assisted reproduction treatments. In this report we describe our experience with sperm washing protocols applied to sperm cells from testicular biopsies as well as the results obtained in subsequent assisted reproduction treatments on seropositive males that are also azoospermic.
Cigarette smoking affects uterine receptiveness
2006
Background Cigarette smoking has long been known to have an effect on female fertility. The existence of an ovarian factor is clear when one considers that the mean age of the menopause is lower and IVF cycle outcome is worse in heavy smokers. The hypothesis of a concomitant uterine effect is raised by indirect evidence from in vitro and in vivo studies, but as yet, no direct evidence has been gained to confirm its existence. In this work, we analyse the association between smoking habit in oocyte recipients and cycle outcome. Methods We have retrospectively analysed the outcome of all oocyte donation cycles performed in our clinic from January 2002 to June 2005 from which there was availab…
Egg donation, surrogate mothering, and cloning: attitudes of men and women in Germany based on a representative survey
2009
Objective To determine opinions and attitudes of the German general population toward the treatment methods of reproductive medicine: egg donation, surrogate mothering, and reproductive cloning. Design Representative survey. Setting German general population: face-to-face interviews at home with 2,110 persons, aged 18–50 years. Patient(s) Patients were not included. Intervention(s) No interventions took place. Main Outcome Measure(s) Approval and disapproval of treatment methods of reproductive medicine and preimplantation genetic diagnosis were assessed by questionnaires regarding medical, age, reasons, or general. Result(s) Overall, the diverse treatment methods of reproductive medicine f…
Monozygotic twinning after assisted reproductive technologies: a case report of asymmetric development and incidence during 19 years in an internatio…
2015
Objective To describe a case of monozygotic twinning with asymmetric development following a single fresh embryo transfer as part of an intracytoplasmic sperm injection (ICSI) treatment. Secondarily, to report the incidence of monozygotic twinning at the IVI (Instituto Valenciano de Infertilidad) clinics. Design Case report. Setting Private fertility centers. Patient(s) A 33-year-old woman with a 2-year history of primary infertility. Intervention(s) Controlled ovarian hyperstimulation and ICSI treatment with single-embryo transfer. Main Outcome Measure(s) Incidence of monozygotic twinning at the IVI clinics. Result(s) We report a twin pregnancy after a single-embryo transfer. Twins were di…
From telescope to binoculars. Dyadic outcome resulting from psychological counselling for infertile couples undergoing ART
2018
Objective This longitudinal study aims to evaluate the effect of psychological counselling on quality of life, marital satisfaction and need for parenthood in couples undergoing fertility treatments (ART). Background Recent guidelines on the ART suggest that psychological counselling should target both members of the infertile couple in order to improve their conjoint management of the infertility-related stress. However, studies on the dyadic outcome of couples are scarce. Methods 262 patients were originally considered in the study and completed questionnaires on quality of life, need for parenthood and marital satisfaction, before treatment (T1) and at the day of intrauterine inseminatio…
Temporal Trend in the Frequency of Ectopic Pregnancies in Lombardy, Italy
2012
<b><i>Background:</i></b> In recent years, epidemiological data showed that the incidence of ectopic pregnancies (EP) is decreasing, but few data are available on the time trend in Southern European populations. <b><i>Methods:</i></b> Using data from the Lombardy Region Database, we calculated and standardized the EP rates/10,000 resident women and the ratios/1,000 pregnancies. <b><i>Results:</i></b> Data regarding 1,777,011 pregnancies and 17,028 cases of EP were recorded among women resident in Lombardy between 1996 and 2010, aged 15-50 years old. The age-adjusted EP rates increased from 4.4 in 1996 to 5.8 in 2010. Th…
